Hi to all,This is my first post on this list. Thanks in advance for every answer.
I've already read every guide in this matter, this is the list: Cluster_Administration.pdf Cluster_Logical_Volume_Manager.pdf Global_Network_Block_Device.pdf Cluster_Suite_Overview.pdf Global_File_System.pdf CLVM.pdf RedHatClusterAdminOverview.pdf The truth is that I've not clear a point about CLVM. Let's me make an example: In this example CLVM and the Cluster suite are fully running without problems. Let's pose the same configuration of cluster.conf and lvm.conf and the nodes of the cluster are joined and operatives. NODE1: pvcreate /dev/hda3 NODE2: pvcreate /dev/hda2 Let's pose that CLVM spans LVM metadata across the cluster, if I stroke the command: pvscan I should see /dev/sda2 and /dev/sda3 and then I can create a vg with vgcreate /dev/sda2 /dev/sda3 ... The question is: How LVM metadata sharing works? I have to use GNBD on the row partion to share a device between nodes? I can create a GFS over a spanned volume group? Are shareable only logical volumes? Thanks for your answers!!
